What does Coulomb's Law state?

• Coulomb's Law only applies to neutral objects
• The force between charged objects is directly proportional to the distance between them
• The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them

• The force between charged objects is inversely proportional to the product of their charges

What is an electric field?

• An electric field is a region where gravity is stronger than electromagnetic forces.
• An electric field is a region where magnetic forces are present.
• An electric field is a region where only neutral objects are affected.
• An electric field is a region around a charged particle where another object experiences a force.
